Pollination is the process of nestinG lifestyles moving pollen from one flower to egg Bees can be organized another of the same species, which honey into two groups produces fertile seeds. Most based on their nesting flowering plants depend on native lifestyle – social and bees for pollination. Bees and solitary. other animals pollinate one-third Social nesting bees, of the food we eat – all kinds of larva social nest like bumble bees, fruits, vegetables, grains, nuts (bumble bee) build communal nests and beans. And they provide us and share division with landscapes filled with of labor including foraging and rearing wonderful wildflowers. of young. They are each Bees are by far the most effective the only native bees cell that nest socially in a pollinators because they feed only contains colony. on flowers.
